Developer Builds Temporary Message-Sharing API Using NestJS, PostgreSQL, and Redis

A developer has published a detailed walkthrough of a temporary message-sharing API built with NestJS, PostgreSQL, Prisma, and Redis. The API lets users create short-lived messages with configurable rules such as expiration windows, visit limits, optional password protection, and one-time access. Each message is assigned a randomly generated short code, and expiration is stored as an absolute timestamp to simplify validity checks at retrieval time. Redis is used for caching, while a scheduled cron job handles automatic cleanup of expired records, and rate limiting is enforced via the NestJS throttler module. The project was intentionally kept small and modular to give each layer — controller, service, database, and cache — a clearly defined responsibility.
